Three heat engines EA, EB and EC receive heat from a reservoir at 627°C and reject heat to a
reservoir at 27°C, as shown in Figure Q2. The thermal efficiency of EA is 0.20 while EB and EC
operate on the Carnot cycle. Determine
i. the power output of engine EA (kW)
ii. the maximum power output of engine Ex when rejecting 100 kW of heat to the sink at 27°C (kW)
iii. the rate of heat supply to engine EB (kW)
iv. the rate of heat rejection from engine EC (kW)
